Abbey D'Agostino of the United States (L) talks with Nikki Hamblin of New Zealand after the Women's 5000m Round 1 - Heat 2 on Day 11 of the Rio 2016 Olympic Games at the Olympic Stadium on August 16, 2016 in Rio de Janeiro, Brazil.

Tuesday in Rio featured at least the fourth engagement of the Olympics, a dramatic 5K finish despite a leg injury and a dive that blew away the competition.

Here are some noteworthy numbers from Day 11 of the Summer Games:

2: The number of Dutch athletes who won open water races at the Rio Games in two days. Ferry Weertman won gold in the men's 10-kilometer swim in the sewage-polluted waters off Copacabana beach on Tuesday. Sharon van Rouwendaal claimed gold for the Netherlands in the women's race on Monday.

2: The number of medals U.S. athletes won in the men's triple jump. Christian Taylor and Will Claye swept gold and silver in the U.S. at back-to-back Olympics. Taylor successfully defended the Olympic title he won in London in 2012, posting the three best jumps of the competition. Claye finished with silver again with a personal record of 17.76.

4: The number of marriage proposals involving athletes at the Games. On Tuesday, Claye got the silver and then proposed to American sprinter Queen Harrison. Claye celebrated his medal by jumping into the stands at the Olympic stadium, getting down on one knee and proposing to Harrison, who said yes. Read about other marriage proposals here.

12: The number of hours it took Kenyan sprinter Carvin Nkanata to travel from Florida to the Olympic Stadium to make the 200-meter heats. Initially ruled ineligible to compete for Kenya, Nkanata appealed, and taking a chance that he would be allowed to run, headed for Rio. He arrived at the Olympic Stadium from the airport just in time to line up, but unfortunately came in last.

17: The age of the youngest American track and field athlete to compete in the Summer Games since 1972. Sydney McLaughlin cut it pretty close Monday night, but she still advanced to the semifinals of the 400-meter hurdles on Tuesday. Her Olympic debut ended there.

17:10.02: The time it took American distance runner Abbey D’Agostino to finish women’s 5000-meter race despite sustaining a leg injury during the race and stopping to check on her rival, Nikki Hamblin of New Zealand, who fell. D’Agostino powered through her injury, limping the last few laps of the race and finishing in 30th place. She didn't advance on time, but after a protest, she earned a spot in the final. Hamblin and a third runner who was affected by the collision, Jennifer Wenth of Austria, also advanced.

28: The number of gold medals up for grabs on Tuesday, including five in track events. Simone Biles won her fourth Olympic gold, this time in the floor exercise. Teammate Aly Raisman earned the silver. Biles' only blemish came Monday night, when she wobbled during the balance beam final and settled for bronze.

54: The age of the oldest medalist at the Rio Games. Santiago Lange, a cancer survivor and six-time Olympian, and crewmember Cecilia Carranza Saroli won the first Olympic gold medal in the Nacra 17 mixed catamaran class at the sailing regatta.

489.10: The numbers of points China's Cao Yuan scored in the semifinals of the men's 3-meter springboard. Yuan blew away the field, finishing with a score of 489.10 points to advance to the evening final. Rommel Pacheco of Mexico was next at 469.70, just ahead of Russia's Evgenii Kuznetsov (468.35) and Mike Hixon of the United States (467.25). Cao will be trying to give China its fifth diving victory in six events at Rio.
